[horde] IMAP Auth with Exchange 2007?

[David Cunningham]

I cannot seem to get any form of auth with IMP to work against  
Exchange 2007.  Is there any secret?  I can telnet to my server on  
either pop3 or imap (110 or 143) and enter credentials by hand without  
issue.  But, those same credentials to do not work when I put them  
into the server config or even in the test script.  I get the  
following from the tests:
